To fix the problem, the code that escapes $, {, and } in the placeholders before constructing a RegExp pattern should use double backslashes ("\\$") in the replacement strings, so that the resultant string has a literal backslash before the meta-character, making it a valid RegExp escape inside the RegExp constructor.

Edit lines 248, 249, and 250 in web/src/utils/dashboard/variables/variablesUtils.ts:

• Change .replace(/\$/g, "\\$") to .replace(/\$/g, "\\\$")
• Change .replace(/\{/g, "\\{") to .replace(/\{/g, "\\{") (unchanged, since { needs a single backslash and this is correct)
• Change .replace(/\}/g, "\\}") to .replace(/\}/g, "\\}") (unchanged, since } needs a single backslash and this is correct)

But wait: Are { and } escaping correct? The same logic applies—when building RegExp pattern strings, it is best to use double backslashes for escaping inside string, which results in a single backslash in the actual RegExp pattern.

So, change:

• .replace(/\$/g, "\\$") to .replace(/\$/g, "\\\$")
• .replace(/\{/g, "\\{") to .replace(/\{/g, "\\\{")
• .replace(/\}/g, "\\}") to .replace(/\}/g, "\\\}")

This will ensure that the resulting RegExp pattern string has escaped characters for $, {, and } as needed to safely and literally match the placeholder strings.

No imports or additional dependencies are required.

To fix the problem, ensure that meta-characters $, {, and } are properly escaped when building a RegExp from a string literal. In JavaScript, this means using double backslashes in string literals so that the final string fed to new RegExp has a single backslash, as required by RegExp syntax. This affects lines 248-250:

• Replace .replace(/\$/g, "\\$") with .replace(/\$/g, "\\\$")
• Replace .replace(/\{/g, "\\{") with .replace(/\{/g, "\\{") (curly brace does not always need escaping unless used in quantifiers, but generally safe to escape as \\{)
• Replace .replace(/\}/g, "\\}") with .replace(/\}/g, "\\}") (same as above)

The most important fix is to ensure that $ is properly escaped as \\$ (string literal), resulting in a single \$ in the RegExp.

Additionally, if any other characters with special meaning in RegExp (like ., *, ^, $, +, ?, (, ), [, ], {, }, |, \) could appear in the variable names or placeholders, consider a generic escape approach (using a utility like escapeRegExp). However, as per the snippet, only $, {, and } are targeted.

No new imports are required; this can be implemented with string replace.

The best way to fix the problem is to remove the unnecessary backslash before $ in the string literal on line 224 (\$${variable.name}). Change it to $${variable.name} so the string matches the dollar sign literally, as intended, without a redundant escape that only makes the code harder to read and possibly misleading.

Make this change only in the construction of the placeholders array, specifically on line 224. No other changes, imports, or definitions are required.

To fix the problem, remove the unnecessary backslash from the dollar sign in the placeholder template on line 224 ('\$' → '$'). This ensures the placeholder string is actually as intended ($variable), and any required escaping for the RegExp string pattern is correctly accomplished by the subsequent replacement step (which replaces all $ with \\$). Only the line constructing the placeholders array needs to be updated in web/src/utils/dashboard/variables/variablesUtils.ts, changing the fifth item (line 224) to use a plain dollar sign. No other changes or imports are required.

To fix the problem, remove the unnecessary backslash escaping in the placeholder string on line 224, changing \$${variable.name} to simply $${variable.name}. Since the code that generates the RegExp pattern string already escapes $ characters on line 248 via .replace(/\$/g, "\\$"), the literal $ will be properly handled in the final RegExp pattern. No other changes are needed, as the escaping logic after this will ensure correctness in the final regular expression. Edit line 224 in web/src/utils/dashboard/variables/variablesUtils.ts, replacing \$${variable.name}, with $${variable.name},.

To fix this issue, we should remove the unnecessary escape character before $ in the placeholder string array on line 224. That is, change \$${variable.name} to $${variable.name} in the placeholders array.
This fix should be made directly at the array construction, as the subsequent code already ensures the correct escaping of $ when building the regular expression pattern. No other code, imports, or refactoring is required.
Change the file web/src/utils/dashboard/variables/variablesUtils.ts, line 224:

• from: \${variable.name}
• to: $${variable.name}

The best fix is to properly escape all RegExp special characters when building a regex from any user-controlled or dynamic string. The standard way to do this is to use a function that escapes all special regex meta-characters—including backslash—in the placeholder string before passing it to new RegExp. This is best achieved by defining an escapeRegExp helper function, such as:

function escapeRegExp(string: string): string {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');
}

Then, replace the current manual escaping with a call to this helper. This change should be made only within the region where the RegExp is constructed—specifically, replace the chained .replace statements on lines 248–250 with a call to escapeRegExp.

Add the new helper function at an appropriate location in the file (often at the top or with other utilities).

The best way to fix the issue is to robustly escape all RegExp meta-characters in the dynamic placeholder string before using it in new RegExp(placeholder, "g"). The core issue is that the code currently uses a series of replace calls to escape certain characters, but misses escaping the backslash itself and any other RegExp special characters. The most robust solution is to use a well-tested escape function, such as escape-string-regexp from npm. Since we may only edit code we've been shown, we can safely add a well-known minimal helper function for escaping RegExp special characters.

For this file, add a local utility function escapeRegExp above this block, and then use it to escape placeholder before passing to RegExp. Remove the custom .replace(/\$/g, "\\$").replace(/\{/g, ...) logic and instead use escapeRegExp(placeholder).

No external npm dependencies are required for the minimal robust escape function. Only this region (lines 245-253) is changed, with the helper inserted earlier in the file.

The best way to fix the problem is to ensure that all occurrences of backslash in the placeholder string are escaped before constructing the dynamic regular expression. This can be done by adding a .replace(/\\/g, "\\\\") call to the chain before the other replacements. Thus, the code should replace placeholder's backslashes to double backslashes, so that the resulting regex is correct. The fix is limited to the region of lines 246-250 in web/src/utils/dashboard/variables/variablesUtils.ts.
