63: Data missing in data URI

You used a data URI. Data URIs in Aneamal are required to contain at least one character in their data part, which your URI does not.

Solution

Define a data URI that contains at least one character after the comma, which marks the start of the data part. Here is an example:

[t]->data:;base64,QQ==

If you do not need to link to or include data, remove the whole data URI.

Address with a comma at the start

A comma at the start of an address is a mark for a base64-encoded textual data URI in Aneamal and is expanded accordingly. For example, [t]->,4pi6 is equivalent to:

[t]->data:;charset=UTF-8;base64,4pi6

If your address is a literal comma and is not meant to be interpreted as data URI, you can prepend the comma with a backslash as in the following example:

[t]->\,
